METHOD FOR PRODUCING LIGHT WAVELENGTH CONVERSION MEMBER, LIGHT WAVELENGTH CONVERSION MEMBER, LIGHT WAVELENGTH CONVERSION COMPONENT AND LIGHT EMITTING DEVICE
A method for producing an optical wavelength conversion member (9) composed of a sintered body containing, as main components, Al2O3 and a component represented by formula A3B5O12:Ce; an optical wavelength conversion member; an optical wavelength conversion component including the optical wavelength conversion member; and a light-emitting device including the optical wavelength conversion member or the optical wavelength conversion component. The production method of the sintered body includes firing in a firing atmosphere having a pressure of 104 Pa or more and an oxygen concentration of 0.8 vol. % or more and less than 25 vol. %.
